WATER-HEATER.

SPECIFICATION forming part of Letters Patent No. 426,157, dated April 22, 1890.

Application filed February l, 1890. Serial No. 338,869. (No model.) Patented in Canada December 2,1889, No. 32,968.

To all whom, it may concern:

Be it known that I, GEORGF ELLS, a subject of the Queen of Great Britain, residing at the city of Montreal, in the district of Montreal and Province of Quebec, Canada, have invented new and useful Improvements in ater-Heaters, (for which I have received Letters Patent in Canada, dated December 2, 1889, No. 32,968,) and Ido hereby declare that the following is a full, clear, and exact description of the same.

My invention relates to improvements in a sectional water-heater in which the fire-pot or furnace is provided with a water-casing having ports in it, one for each of the sections to connect with, the sections being in the form of a serpentine tube, around which the products of combustion circulate. The sections each unite with an upper section, forming the top of the water-heater. This is provided with openings for the products of combustion to pass through, and over it is placed a sn1oke-hox. The said top is also provided with a damper, by which the draft is regulated; and the objects of my improvements are, first, to form aheater having a large amount of very active heating-surface; second, to provide for a free circulation of the water therein; third, to give free access for sweeping and cleaning the heating-surfaoes, fourth, to enable any of the sections f or g to be 1'en1oved.,if desired, without having to disconnectthe other sections oran'y of thewater-pipes and smoke-pipe of the heater; fifth, to so arrange the damper that the heated gases will be confined within the water-heater. I attain these objects by the water-heater illustrated in the accompanying drawings, in which similar letters and numerals of reference indicate like parts.

Figure 1 is a side elevation of the waterheater. Fig. 2 is a half front elevation and half vertical section of the water heater, the sectional part being taken on line a; 9:, Fig. 3. Fig. 3 is a longitudinal vertical section of the water-heater, taken on line 09 a), 2. Fig. 4 is a plan of the upper section or top h and damper 21 in position therewith. Fig. 5 is a plan of the damper 21 detached. Fig. 6 is a half plan of the fire pot or furnace and a half plan of the same, with sections f and g in place thereon. Figs. 7 and S are side elevations of the sections f and g detached.

Letter a is an ordinary water-cased furnace or fire-pot, at the front of which is a fire-hole I), provided with an ordinary door 0.

c are the hubs or openings, to which are connected the inlet or return ends of the hotwater-circulatin g pipes.

At the back of the furnace, and at the top thereof, an enlargement dis formed to give a suitable surface for attaching the lower surface of the sections f and g upon by means of bolts and nuts 1. Also ports 2 are formed, one for each of the sections f and g.

c are any ordinary gratebars, and e an ordinary ash-pit.

The furnace a may be arranged to have any number of individual sections f united therewith. As shown, there are seven f and g. The sections f consist each of a serpentine tube, preferably having flat sides and a rounded top and bottom, with spaces 3 and t for the products of combustion to circulate in, and thus cause the surfaces of these sec tions to be very effective for heating the water contained in them. They are each provided with a projection or enlargement 5, by which they are attached by the bolts and nuts 1 to the furnace, having also each at their lower extremity a port 6 agreeing with one of the ports 2. Each of the sections f has a back flange 7 of such size that when the sections are in place on the furnace a they form the back wall of that part of the heater between the projections 5 and upper section or top 71. The sections 9 are constructed exactly like the sections f, only as they are the outer sections they are made in conjunction with a web, plate, or flange 8, which extends from the front to the back flange 7 and from the top of the furnace a to the bottom of the top or upper section 71. The webs 8 are provided with openings 15 for cleaning such portions of the sections f and g, that cannot be conveniently reached when the door 16 at the front is opened. 17 are ordinary covers to the openings 15. The upper extremity of both the sections f and g are terminated each in a face 9, having a port connected with corresponding ports 11, formed (one for each section) on the under side of the upper section or top h. The sections f and g are also each provided with a projection 12, through which and the front wall 13 of the top h the bolts 14: pass, uniting the sections f and g with the top h.

The upper section or top h consists of a fiat rectangular Water-casing in addition to the ports 11, described above, and a number of elongated openings 18 (as shown there are three) for the products of coinbustionfrom the furnace a, to pass through into the smoke-box 19. The upper section or top'h is extended at the back, as shown, and on this extension are formed the ordinary hubs h, to which the outlet or hot water-circulating pipes 20 are connected in the ordinary manner.

On the upper surface of the upper section or top h is laid a damper 21. This consists of a plate of metal having openings 22 formed to agree with the openings 18; but to prevent these from being entirely closed by the damper, and thus cause the products of combustion to be distributed in the place in which the water-heater is situated, I form these With the enlargements 23 of suitable size, so that while the draft is effectively checked there is yet sufficient vent to carry off the gases and smoke.

The smoke-box 19 is provided with a door 24, by which it may be cleaned.

What I claim is as follows:

1. The combination, in a \vater-hcater, of

ing ports for the top of each of the sections f and g to connectwith, also having openings 18 for the products of combustion to pass through the whole, substantially as and for the purposes set forth.

2. The combination, in a Water-heater, of the furnace inclosed in a water-jacket having ports 2, one for each of the sectionsfand g to individually connect with, With vertical sections f and g, constructed in one piece of serpentire form and having flange 7 adapted to form a portion of the outer casing of the Waterheater, vertical sections g, having flanges 7 and 8 adapted to form a portion of the outercasin got the Water-heater, and bolts 1 and 14, by which the sections are individually attached in place and may be individually removed, with top or upper section h, having ports for the sections f and g to individually connect with, the whole substantially as described.
